I will watch the video tonight, but judging by the amount of code in the thumbnail, I will go out on a limb and say that it looks authentic.

And yes, it is CS, but might have a lot of math in it, which will only legitimately work if the student is prepared for it. And I have already previously stated that generally means algebra (could be concurrently).

Btw, I have seen students brought up on black box GUI programming (no code, just mouse clicks) and they are usually extremely limited (severely) in their thinking and ability. Those who have code (text) in their background are usually not, and can also use black box products when needed.
